Patent JP-S60224268-A (JP)
Title: Power semiconductor element
Inventor: ISHIBASHI SATOSHI
IPC: H01L29/74
Filed: 1984-04-20
Abstract: PURPOSE:To reduce a bevel region required for machining of end surface to a large extent and to provide the effective conducting cross sectional area of a wafer efficiently, by forming an angle at a junction with respect to the main surface of the wafer, and forming the end surface of the junction at an angle larger than said angle with respect to the main surface. CONSTITUTION:In a P-N junction element requiring a negative bevel, an angle alpha1 is formed with respect to a main surface MS before the P-N junction is formed, in a semiconductor element region, whose end surface is machined at the later angle lapping process. Said angle alpha1 can be formed by polishing the angle at the outer surface of the wafer before diffusion or by partially forming a groove by using an anisotropic etching. After the angle polishing, diffusion for forming junctions J2 and J1 is performed, and the P-N junction is formed. Thereafter, the end surface is cut to obtain an angle alpha2 on the side where a negative bevel is formed with respect to a main surfaces MS of the wafer. At this time, a negative bevel angle theta2 between the negative bevel and the end surface becomes theta2=alpha2-alpha1. The angle theta2 is set at several degrees.

Title: Noise muffling device
Inventor: INAHATA TADAO
IPC: G10K11/16
Filed: 1987-04-03
Abstract: PURPOSE:To improve noise muffling effect by permitting a noise wave propagating in a waveguide chamber to resonate with a fluid oscillation system in a resonance noise muffling chamber via a communicating part. CONSTITUTION:Hammering noise generated following the printing action of a printer is propagated to a waveguide chamber 20 partitioned between a sleeve member 11 and an inner cylindrical member 12 through a rubber roller and the sleeve member 11 of a platen, and further is propagated in the waveguide chamber 20. The frequency of a main component of this propagating sound wave coincides with an intrinsic frequency of the oscillation system of an air column in a resonance noise muffling chamber 30 which communicates with the waveguide chamber 20 via a slit 12a and is partitioned by the inner cylindrical member 12. Therefore, said noise wave enters the resonance noise muffling chamber 30, resonating with an air column oscillation system in said chamber. A sound wave energy is converted to a thermal energy subsequent to the resonance phenomenon, resulting in the loss of energy and reduction of the noise level of hammering noise.

Title: Digital video signal recorder
Inventor: MURATA NORIO
IPC: H04N19/46
Filed: 1989-04-03
Abstract: PURPOSE:To record and regenerate all NTSC signals with a correct hue by constituting a recorder so that both of the fall timing of a horizontal synchronizing pulse an the phase of a burst signal reflect on the selection of an effective video signal period. CONSTITUTION:The horizontal synchronizing pulse separated by a synchronization separating circuit 21 is synchronized with the leading edge of the subcarrier pulse extracted from the burst signal when a pulse required to instruct the effective period of the video signal to a data blocking circuit 5 is generated by a synchronous circuit 300. Consequently, burst information is reflected on the selection of the effective period of the video signal recorded on a VTR. Further, the color frame of the NTSC signal is determined by a frame deciding circuit in accordance with the vertical synchronizing pulse obtained by the synchronization separating circuit 21, the horizontal synchronizing pulse whose edge is synchronized, and the subscarrier pulse, and this color frame information is sent to a parity ID adding circuit 6, and thereby, the signal recorded as a first frame is regenerated as the signal of the first frame, and the video signal is correctly recorded and regenerated.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a communication system which prevents the leakage of a key file that is used in utilizing a virtual dedicated line to a third person. SOLUTION: When a user loads an IC and 30 that stores his own key file into a card reader/writer 75, a communication terminal 2a detects IC card loading and expands the key file in memory 73 when user authentication is performed with a password. When a user ID is preliminarily registered in an IC card issue registration system 1, authentication check is performed with member service, and when it is valid, a VPN server that constructs a virtual dedicated line is started and constructs a virtual dedicated line VT between the terminal 2a and a DB server (target server) and communication is available. When the card 30 is unloaded or when the communication is over, the key file is eliminated from the memory 73 and leakage to a third person is prevented.

Abstract: PURPOSE:To discriminate exactly whether call voltages Va, Vb are high or low, by providing a variable attenuating element on an input side of an auxiliary amplifying circuit of the call voltages Va, Vb of east bound and west bound, and giving the same attenuation quantity to each call voltage Va, Vb. CONSTITUTION:Call voltages Va, Vb are attenuated by variable attenuating elements 11a, 11b, amplified, rectified and smoothed, become DC voltages, and applied to a capacitor 9. This voltage is inputted to an amplifier 10, the voltage is proportional to Va+Vb, and a current being proportional to it is supplied in parallel to a control terminal (q) of the attenuating elements 11a, 11b from an output terminal. Accordingly, the total gain of the cascaded attenuating elements and an auxiliary amplifying circuit is the same with regard to both channels. In case when a value of one or both of the call voltages Va, Vb is large remarkably, a large control current from the amplifier 10 flows in from the terminal (q) of the attenuating elements 11a, 11b and its attenuation quantity drops, auxiliary amplifying circuits 1a, 1b can be operated within a linear range, and whether the call voltages Va, Vb are high or low can be discriminated exactly.

IPC: H03H15/00
Filed: 1989-03-31
Abstract: PURPOSE:To attain efficient peak shift compensation by compensating peak shift by a preshifting circuit and an equalizing circuit and forming a pair of equalizing signals having respectively different equalizing amounts by the equalizing circuit. CONSTITUTION:The magnetic recording and reproducing circuit is constituted of the preshifting circuit 1 for executing peak shift compensation at the time of recording, the equalizing circuit 5 for executing peak shift compensation at the time of reproducing and a digital reproducing circuit 6. Since the circuit 5 is constituted so as to include a pair of equalizers, equalizing signals having respectively different equalizing amounts can be formed. Since the equalizing signal inputted to a differential means in the circuit 6 is set up so as to compensate the residual of the peak shift compensation executed by the circuit 1, its equalizing amount is set up to a small value. On the other hand, the equalizing amount of the equalizing signal inputted to the window signal forming means in the circuit 6 is set up to a large value so as to compensate the drop of a peak level due to high recording frequency. Thereby, the preshifting amount of the circuit 1 and the equalizing amounts of a pair of equalizers can be respectively set up. Consequently, efficient peak shift compensation can be executed.

Title: Production of oxide superconductor
Inventor: NAGAYA SHIGEO
IPC: C30B29/22
Filed: 1989-03-31
Abstract: PURPOSE:To obtain the title superconductor with its crystal unidirectionally solidified throughout the width direction of the film by irradiating an oxide superconducting substance with laser beams at a specified tilt angle against said width direction to effect melting said substance followed by cooling and crystallization. CONSTITUTION:A thin film 1 of an oxide superconducting substance or a substance capable of forming the same by melting and sintering is formed on a continuous base 2. The film 1 is then irradiated with laser beams 3 at a tilt angle against the scanning direction; during the process, a scanning is made in the arrow A direction to heat and melt the irradiated zone 1a. As the laser beams 3 move, the melted zone is cooled from behind to effect recrystallization. The irradiation angle theta of the laser beams is regulated so as to accomplish an optimum orientation according to laser output and film thickness. Thereby, the zone 1a begins to cool from behind successively, however, there is no temperature gradient in the width direction at a part where cooling begins and a nearly uniform temperature has been attained, thus crystal will grow parallel to the film surface in the scanning direction.
